The wave slap mention may not be as bad on the mod v. My flat bottom can get noisey if its a little choppy from wind even at very slow speeds. Something else to consider when deciding between the two is floor space. I sent an email to Alumacraft when I was trying to decide between the two (which I still haven't bought a new boat YET). They told me that the flat and mod-v draft about the same amount or water but you loose a little floor space in the mod-v. I'm not sure how much you loose though. Might not be enough to make a difference.
